 ## Why Docket?
 
 - **No servers, no network** — everything is a local SQLite file in `.docket/`. Works offline, on planes, in CI.
-- **AI-native from day one** — every command supports `--json` with a consistent envelope. Agents can create, query, plan, and update issues without parsing human text.
+- **AI-native from day one** — machine-readable commands support `--json` with a consistent envelope. Agents can create, query, plan, and update issues without parsing human text.
 - **Dependency-aware planning** — `docket next` and `docket plan` use a DAG to surface only unblocked, work-ready issues. No stale sprint boards.
 - **Zero configuration** — `docket init` and you're done. No accounts, no tokens, no YAML.
 - **Portable data** — the `.docket/` directory travels with your repo. Clone it, fork it, archive it.

 Any agent that can run shell commands works with Docket. Point it at `docket next --json` to discover work items, and use `docket issue show <id> --json` to get full context before starting a task. The consistent JSON envelope (`ok`, `data`, `error`, `code`) makes parsing straightforward in any language.
 
+### Interactive UI
+
+Use `docket ui` when you want an interactive browser instead of command output. It opens a read-only terminal UI for list and board browsing, requires an interactive terminal, and does not support `--json`.
+
+If you need to debug terminal-specific behavior, set `DOCKET_UI_DEBUG_LOG=/tmp/docket-ui.log` before running `docket ui`.

@@ -69,15 +69,16 @@ The following dimensions are weighted by their relevance to the docket project,
 - Review must verify: migration idempotency, rollback safety, data preservation across versions
 
 **JSON API Contract Stability (Critical)**
-- Every command supports `--json` with a documented envelope (`{"ok": true, "data": ..., "message": ...}`)
+- Non-interactive commands support `--json` with a documented envelope (`{"ok": true, "data": ..., "message": ...}`)
 - AI agents depend on stable JSON shapes — breaking changes silently break agent workflows
+- Interactive commands like `docket ui` are exceptions and must fail clearly when `--json` is unsupported
 - Error codes (`GENERAL_ERROR`, `NOT_FOUND`, `VALIDATION_ERROR`, `CONFLICT`) are part of the contract
 - The QA suite has dedicated sections (Q, R) for contract and exit code validation
 - Review must verify: no field renames/removals without versioning, exit codes match documented behavior
 
 **CLI UX Consistency (High)**
 - One-file-per-command pattern in `internal/cli/` must be maintained
-- All commands must support `--json` and `--quiet` flags via `getWriter()`
+- Non-interactive commands should support `--json` and `--quiet` via `getWriter()`; interactive commands must document and enforce any exceptions
 - Interactive forms (via `charmbracelet/huh`) must degrade gracefully in non-TTY contexts
 - Review must verify: new commands follow established patterns, help text is consistent
